And yet another one: Crime inquiry said to open on Citigroup

From the New York Times:

Just as Citigroup was putting a troubled past of taxpayer bailouts and risky investments behind it, the bank now finds itself in the government’s cross hairs again.

Federal authorities have opened a criminal investigation into a recent $400 million fraud involving Citigroup’s Mexican unit, according to people briefed on the matter, one of a handful of government inquiries looming over the giant bank.

The investigation, overseen by the F.B.I. and prosecutors from the United States attorney’s office in Manhattan, is focusing in part on whether holes in the bank’s internal controls contributed to the fraud in Mexico. The question for investigators is whether Citigroup — as other banks have been accused of doing in the context of money laundering — ignored warning signs.
